Keep Calm & T-shirts: the old mantra lives on

And mug. What? Yes: the message is to keep calm. And you can print it on Keep Calm mugs to spread the word, or Keep Calm T-shirts to let people know in tube stations, football stadiums, festivals, crowded bars or any other place where it’s important to keep calm. And carry on. And dance, drink whisky, be a unicorn and kill zombies.
